<p>A method for arbitrating audio signal output used in a portable electronic device, which comprises a speaker and two independent voice communication systems. When one voice communication system needs to send out a ringing signal, the voice communication system first detects the status of the other voice communication system. If the other voice communication system is idle, the ringing signal is sent out via the speaker; if the other voice communication system is in use, the ringing signal is not sent out, and an optional prompting signal is sent out via a receiver.</p> |
